Let's divide 58100073 by 45
We're looking to find how many times 45 goes into 58100073.

Moving on to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 45

Step 2:
When dividing 58 by 45, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 58 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 45

Going ahead to step 3:
45 goes into 131 2 times with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 90 from 131, we get 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 45

Let's proceed to step 4:
If we divide 410 by 45, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we take 405 away from 410, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 45

Let's proceed to step 5:
50 divided by 45 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1291.0
The remainder is 5 after subtracting 45 from 50.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 45

Moving on to step 6:
50 divided by 45 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 12911.0
If we take 45 away from 50, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 45

Going ahead to step 7:
45 goes into 57 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 129111.0
Deduct 45 from 57 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 45

On to step 8:
If we divide 123 by 45, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 1291112.0
Deduct 90 from 123 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
When dividing 330 by 45, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 1291112.7
Deduct 315 from 330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 1291112.73
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 1291112.733
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 1291112.733, and the remainder is 0.0015.
